Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims the benefit of U.S. Provisional Application No. 63 / 440,626, filed on January 23, 2023. The entire disclosure of the above application is incorporated herein by reference. Technical Field

[0003] The present disclosure relates to food preservation and warming equipment and, more particularly, to humidity management systems for such equipment. Background Art

[0004] This section provides background information related to the present disclosure which is not necessarily prior art.

[0005] Food holding and warming cabinets are known in the food service industry and are used to keep prepared foods ready for consumption by keeping them at the proper temperature without compromising the quality of the food.

[0006] Small food preservation and warming cabinets are sized to accommodate vertically stacked steam portion pans and / or flat bottom portion pans. The floor space of these cabinets makes them desirable in kitchens with limited space, or allows these cabinets to be placed close to the point of use, such as on or below the top of a table or workbench. In addition, small food preservation and warming cabinets are advantageous when it is necessary to preserve small amounts of food or a variety of foods with different preservation and / or warming requirements.

[0007] The relative humidity in a holding cabinet can vary widely, depending on the type and amount of food being held, how the food is prepared, and how long the food is held in the cabinet before being consumed. In order to maintain the quality of the food during storage, a certain degree of control over the relative humidity in the cabinet's holding environment is required. In some cases, too high a relative humidity can cause crispy foods to become soft or soggy, while in other cases, too low a humidity can cause the food to dry out.

[0008] Known heated storage cabinets may include one or more manual vents that can be opened or closed to passively address humidity control issues, such as by allowing or preventing humid air from escaping the cabinet storage environment. Other known cabinets include closed-loop automation systems that are programmed to maintain the relative humidity in the cabinet storage environment at a desired relative humidity set point. Utility Model Content

[0009] This section provides a general summary of the disclosure, and is not a comprehensive disclosure of its full scope or all of its features.

[0010] The present disclosure provides a food preservation and warming cabinet, characterized in that it comprises:

[0011] an insulated housing defining an enclosed interior space for containing food;

[0012] a first ventilation chamber, the first ventilation chamber being adjacent to the enclosed interior space and comprising a first ventilation opening and a second ventilation opening, the first ventilation opening being located between the first ventilation chamber and the enclosed interior space, the second ventilation opening ventilating the first ventilation chamber from the surrounding environment outside the cabinet;

[0013] a conduit extending between the plenum and the enclosed interior space;

[0014] a door attached to the housing and movable between an open position providing access to the enclosed interior space and a closed position preventing access to the enclosed interior space;

[0015] A heating system for heating the enclosed interior space and comprising a convection heating component and a radiation heating component, wherein the convection heating component comprises:

[0016] a first heating element located within the conduit; and

[0017] a fan positioned in the first ventilation chamber proximate to the first ventilation opening;

[0018] the fan being operable to create a negative pressure within the enclosed interior space so that air circulates through the conduit, past the first heating element and into the enclosed interior space;

[0019] The radiant heating component has a second heating element disposed within the enclosed interior space; and

[0020] A user-operated humidity management system, the humidity management system comprising:

[0021] a second plenum chamber positioned adjacent to the first plenum chamber and comprising: a third vent opening leading from the second plenum chamber to an ambient environment outside the cabinet; and

[0022] A baffle member selectively separates the second ventilation chamber from the first ventilation chamber, and the baffle member is capable of moving between an open state and a closed state, in which the open state allows air flow between the first ventilation chamber and the second ventilation chamber, and in the closed state prevents air flow between the first ventilation chamber and the second ventilation chamber.

[0023] The present disclosure provides a small food preservation and warming cabinet including a user-operated humidity management system.

[0024] In one aspect of the present disclosure, a food storage and warming cabinet employs a hybrid heating system that includes both hot air convection heating components and radiant heating components. The combination of convection heating and radiant heating provides a more uniform heat distribution throughout the cabinet storage environment.

[0025] In another aspect of the present disclosure, a user-operated humidity management system enables a user to manually control the introduction of moisture into the cabinet storage environment or the reduction or decrease of humidity within the cabinet storage environment. Moisture can be introduced into the cabinet storage environment by evaporation. In this regard, the radiant heating element can be used to heat a water basin (e.g., a steam basin or water pot) placed adjacent to or in proximity to the radiant heating element at or near the bottom or floor of the cabinet storage environment.

[0026] Alternatively, the humidity in the cabinet storage environment can be lowered or reduced by directing the hot and humid air circulating through the cabinet storage environment to the outlet vents at the upper end of the cabinet. In addition, an intake vent can be included at the lower end of the cabinet door, which, when opened, introduces ambient air from outside the cabinet storage environment into the hot air flow circulating through the cabinet storage environment to further help reduce humidity.

[0027] In another aspect of the present disclosure, an arrangement of a plurality of food holding and warming cabinets is provided.

[0028] In another aspect of the present disclosure, a bracket may be employed to enable easy combination of multiple cabinets into a stacked arrangement.

[0029] In another aspect of the present disclosure, the food holding and warming cabinet can have various sizes, can be fixed or mobile, and / or be suitable for use in various environments or applications, such as suitable for use on counters, under counters, wheels, and transportation.

[0030] Further areas of applicability will become apparent from the description provided herein.The description and specific examples in this summary are intended for purposes of illustration only and are not intended to limit the scope of the present disclosure. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] Example embodiments will now be described more fully with reference to the accompanying drawings.

[0040] Figures 1 to 6 A food preservation and warming cabinet according to the present disclosure is illustrated. The food preservation and warming cabinet 10 includes an insulated cabinet housing 12 having a plurality of housing walls, namely a first side wall 14, a rear wall 16, a second side wall 18, and a front side wall 20. The housing walls (i.e., the first side wall 14, the rear wall 16, the second side wall 18, and the front side wall 20) enclose an interior space 22 of the food preservation and warming cabinet 10 to accommodate food. The enclosed interior space 22 is defined by the first and second side walls 14, 18, the rear wall 16, the top wall 24, and the bottom plate 26 that are opposite. At least one of the side walls, i.e., the first side wall 14, includes or accommodates a duct or chimney 28 located within the first side wall 14, which is in communication with the enclosed interior space 22. The first side wall 14 and the second side wall 18 may include a tray rail 30 to support a basin or tray (e.g., a portion basin) for accommodating food stored in the food preservation and warming cabinet 10.

[0041] The front side wall 20 of the housing provides an opening 32 leading to the enclosed interior space 22. A door 34 is attached to the front side wall 20 of the housing and is movable between an open position for providing access to the enclosed interior space 22 and a closed position for preventing access to the enclosed interior space 22 and sealing the enclosed interior space 22 from the surrounding environment outside the food holding and warming cabinet 10.

[0042] Located above the top wall 24 of the enclosed interior space 22 is a first ventilation chamber 40. The first ventilation chamber 40 is in fluid communication with the duct 28 in the first side wall 14. The first ventilation chamber 40 also includes a first ventilation opening 42 in fluid communication with the enclosed interior space 22. A fan 44 is disposed in the first ventilation chamber 40 near the first ventilation opening 42. For example, the air inlet side of the fan 44 can be located directly above the first ventilation opening 42. The first ventilation opening 42 enables the fan 44 to circulate air between the enclosed interior space 22 and the first ventilation chamber 40, as further discussed. A second ventilation opening 46 is used to reduce the temperature of the top of the food storage and warming cabinet to protect electronic components.

[0043] The food holding and warming cabinet 10 also includes a heating system 50 for heating the enclosed interior space 22. The heating system 50 may include both a convection heating element 52 and a radiant heating element 54.

[0044] The convection heating element 52 utilizes the circulating hot air in and through the enclosed interior space 22 to heat the enclosed interior space 22 (and / or the food stored therein) to a desired temperature. The convection heating element 52 includes a first heating element 56 (i.e., a resistive heater) located in the conduit 28 of the first side wall 14. In operation, the fan 44 draws air from the enclosed interior space 22 through the first ventilation opening 42 and creates a negative pressure in the enclosed interior space 22. When this occurs, the air is drawn through and / or into the first ventilation chamber 40 and into the conduit 28. As the air circulates into and through the conduit 28, the air necessarily approaches the first heating element 56 and / or passes through and / or passes through the first heating element 56, and the air is heated. The hot air then continues to circulate into and through the enclosed interior space 22, thereby heating the space and / or the food to a desired temperature or maintaining the space and / or the food at a desired temperature.

[0045] Optionally, in addition, the heating system may further include a radiant heating component 54. The radiant heating component 54 may include a second heating element 58, which is disposed at, near or in the floor of the enclosed interior space 22.

[0046] The radiant heating element 54 and the convection heating element 52 may be operated independently, alternately, and / or in combination to achieve even and consistent heat distribution throughout the enclosed interior space 22 of the food holding and warming cabinet 10 .

[0047] As shown in the figure, especially Figures 2 to 4 as well as FIG. 5A to FIG. 5C As shown in FIG. 1 , the food holding and warming cabinet 10 of the present disclosure may include a user-operated humidity management system.

[0048] Reference Figure 5A , the humidity management system can utilize the radiant heating element 54 to introduce moisture into the enclosed interior space 22 to increase the relative humidity. In this regard, a water pan 62 (e.g., a basin containing water) can be placed in the enclosed interior space 22 on or near the second heating element 58. The second heating element 58 can heat the water pan 62 to generate water vapor or steam, which can be introduced into the enclosed interior space 22 to increase the relative humidity in the enclosed interior space 22. In addition, the circulating flow of hot air can also heat the water pan 62 and / or mix with the water vapor or steam into the air flow and help distribute the increased moisture throughout the enclosed interior space 22.

[0049] Reference Figures 2 to 4 , Figure 5A , Figure 5B and Figure 5C The humidity management system may also reduce the humidity (ie, lower the relative humidity) of the enclosed interior space 22 of the food holding and warming cabinet 10, which may be manually controlled and / or manipulated by the user / operator.

[0050] The humidity management system is located above the top wall 24 of the enclosed interior space 22 of the food preservation and warming cabinet 10 and adjacent to the first ventilation chamber 40. The humidity management system may include a second ventilation chamber 60. In the case where the second ventilation chamber 60 has an opening, the first ventilation chamber 40 is under positive pressure. This allows moisture to be eliminated. The second ventilation chamber 60 may include a third ventilation opening 66 (i.e., an outlet vent) that leads from the second ventilation chamber 60 to the surrounding environment outside the food preservation and warming cabinet 10. Preferably, the third ventilation opening 66 is provided at the rear of the food preservation and warming cabinet 10. In addition, the second ventilation chamber 60 may include a baffle member 68 that selectively separates the second ventilation chamber 60 from the first ventilation chamber 40. The baffle member 68 can move between an open state and a closed state, in which the air flow between the first ventilation chamber 40 and the second ventilation chamber 60 is allowed, and in which the air flow between the first ventilation chamber 40 and the second ventilation chamber 60 is blocked. A shutter operator 70 may be coupled to the shutter member 68 and accessible to a user / operator. The shutter operator 70 enables the user / operator to manipulate the shutter member 68 between an open state and a closed state.

[0051] Further references Figure 2 , Figure 5A , Figure 5B and Figure 5C , the first ventilation chamber 40 may include a chamber wall 72 having at least one first slot 74, and preferably a plurality of first slots passing through the chamber wall. The baffle member 68 in turn includes at least one second slot 76, and preferably a plurality of second slots passing through the baffle member 68. The baffle member 68 may be positioned against the chamber wall 72. The baffle member 68 is movable (e.g., slidable) relative to the chamber wall 72. Preferably, the chamber wall 72 and the baffle member 68 are positioned proximate to the first ventilation opening and / or the exhaust side of the fan 44.

[0052] Reference Figure 5C In the open state of the baffle member 68, at least one second slot 76 is at least partially aligned with at least one first slot 74; that is, the first slot 74 and the second slot 76 at least partially overlap, so that an air passage between the first ventilation chamber 40 and the second ventilation chamber 60 is formed through the first slot 74 and the second slot 76. In the closed state of the baffle member 68, at least one second slot 76 is not aligned with at least one first slot 74; that is, the first slot and the second slot do not overlap. Figure 5B As shown in FIG. 7 , in the closed state, the first ventilation chamber 40 and the second ventilation chamber 60 are closed to each other, and air does not flow from the first ventilation chamber 40 to the second ventilation chamber 60 through the first slots 74 and the second slots 76 .

[0053] It will be appreciated that the user / operator can manipulate the flapper operator 70 to control the amount of overlap between the first slot and the second slot. Thus, the user / operator can selectively move the flapper member 68 from a closed state (i.e., no overlap between the first slot 74 and the second slot 76) through at least a plurality of partially open states (i.e., the amount of overlap between the first slot 74 and the second slot 76 is greater than zero but less than a maximum amount) to a fully open state (i.e., the amount of overlap between the first slot and the second slot is at a maximum amount). In addition, the flapper operator 70 can be associated with a preset flapper position or indicia to assist the user / operator when the user / operator manipulates the flapper operator 70 to change the opening between the first vent chamber and the second vent chamber and, therefore, the airflow.

[0054] like Figure 5C As shown in , the humidity of the enclosed interior space 22 of the food holding and warming cabinet 10 can be reduced by the user / operator moving the baffle member 68 to the open state. In this regard, air with a relative humidity higher than a desired value from the enclosed interior space 22 of the food holding and warming cabinet 10 can be discharged to the surrounding environment outside the food holding and warming cabinet 10 through the second ventilation chamber 60. For example, when the baffle member 68 is in the open state, the humid air drawn into the first ventilation chamber 40 from the enclosed interior space 22 by the fan 44 can pass through the aligned first slot 74 and second slot 76 of the chamber wall 72 and the baffle member 68, and enter the second ventilation chamber 60. The humid air can pass from the second ventilation chamber 60 through the third ventilation opening 66 and reach the external surrounding environment. The replacement air can be drawn through the door ventilation assembly 80 as described below.

[0055] Reference Figure 3 , Figure 4 and Figure 5C , the food holding and warming cabinet 10 has a door 34 attached to the front of the cabinet housing 12. The door 34 may include a door ventilation assembly 80, which may optionally be part of a humidity management system.

[0056] like Figure 4 As seen in the figure, the door 34 includes a door frame 82, and a door ventilation assembly 80 is attached to the door frame 82. The door ventilation assembly 80 may include a door ventilation member 84 having at least one third slot 86 passing through the door ventilation member 84, a door ventilation damper member 88 having at least one fourth slot 90 passing through the door ventilation damper member 88, a door ventilation body 92, and a door ventilation operator 94 for opening and closing the door ventilation assembly 80.

[0057] The door ventilation member 84 is attached to the door frame 82 near the bottom of the door frame. The at least one third slot 86 of the door ventilation member 84 leads to the enclosed interior space 22 of the food holding and warming cabinet 10.

[0058] The door vent flap member 88 is located adjacent to (e.g., against) the door vent member 84. The at least one fourth slot 90 of the door vent flap member 88 is open to the external ambient environment. The door vent flap member 88 can move (e.g., slide) relative to the door vent member 84 between an open state and a closed state. The door vent operator 94 enables a user / operator to manipulate the door vent flap member between the open state and the closed state.

[0059] In the open state, Figure 5C As shown in FIG, at least one fourth slot 90 of the door ventilation damper member 88 is at least partially aligned with at least one third slot 86 of the door ventilation member 84; that is, the third slot 86 and the fourth slot 90 at least partially overlap, so that an air passage between the external ambient environment and the enclosed interior space 22 is formed by the third slot 86 and the fourth slot 90. In the closed state of the door ventilation damper member 88, the at least one fourth slot 90 is not aligned with the at least one third slot 86; that is, the third slot 86 and the fourth slot 90 do not overlap, and the external ambient environment is isolated from the enclosed interior space by the door ventilation assembly 80.

[0060] Similar to what was previously discussed, it will be appreciated that a user / operator can manipulate the door vent operator 94 to control the amount of overlap between the third slot 86 and the fourth slot 90. Thus, the user / operator can selectively move the door vent damper member 88 from a closed state (i.e., no overlap between the third slot 86 and the fourth slot 90) through at least a plurality of partially open states (i.e., the amount of overlap between the third slot 86 and the fourth slot 90 is greater than zero but less than a maximum amount) to a fully open state (i.e., the amount of overlap between the third slot 86 and the fourth slot 90 is at a maximum amount). In addition, the door vent operator 94 can be associated with a preset position or indicia to assist the user / operator when the user / operator manipulates the door vent operator 94 to open the door vent assembly 80.

[0061] When the door 34 of the food preservation and warming cabinet 10 remains closed, the door ventilation assembly 80 can help reduce humidity. In this regard, air (e.g., outside air) from the external ambient environment with a humidity lower than the air in the enclosed interior space 22 of the food preservation and warming cabinet 10 can be introduced into the enclosed interior space 22 of the food preservation and warming cabinet 10 by opening the door ventilation assembly 80. As previously discussed, the outside air can then circulate through the food preservation and warming cabinet 10. When the third ventilation opening 66 of the food preservation and warming cabinet is opened and the door ventilation assembly 80 is not opened, the air leaving the third ventilation opening 66 at the rear will generate a negative pressure inside the enclosed interior space 22 of the food preservation and warming cabinet 10. This limits the amount of humid air removed. By opening the door ventilation assembly 80 and the third ventilation opening 66 of the food preservation and warming cabinet, the cross flow reduces the negative pressure and allows more humid air to escape.

[0062] Reference Figure 6 , showing an arrangement structure of a plurality of food holding and warming cabinets 10 of the present disclosure. A first (upper) food holding and warming cabinet 100 can be stacked on a second (lower) food holding and warming cabinet 102. In order to fix the stacked arrangement structure of the cabinets, a stacking bracket 110 can be provided between the first food holding and warming cabinet 100 and the second food holding and warming cabinet 102. Although only two cabinets using one stacking bracket 110 are shown in the stacked arrangement structure in FIG. 5, it can be understood that more than two cabinets using more than one stacking bracket can be arranged in this way.

[0063] The stacking rack 110 may include at least one vertical side wall 112 and at least one horizontal flange 114. As shown, the stacking rack has four side walls - two opposing tall side walls, namely a first tall side wall 116 and a second tall side wall 118, and two opposing short side walls, namely a first short side wall 120 and a second short side wall 122. Some or all of the side walls may include vents 124, which include one or more slots 126 that allow air to flow into and out of the space enclosed by the stacking rack 110 between the stacked cabinets (i.e., ventilation). Each side wall includes a horizontal flange 114 located at the lower end of the first tall side wall 116 and the second tall side wall 118. The stacking rack is fastened to the upper end 128 of the second (lower) food holding and warming cabinet 102 at the horizontal flange 114 (e.g., with threaded fasteners). Additionally, the stacking rack 110 is fastened (eg, with threaded fasteners) to the lower end 130 of the first (upper) food holding and warming cabinet 100 at the vertical sidewalls.

[0064] As shown in the figures, the food holding and warming cabinet 10 of the present disclosure can be configured to be stationary (eg, having cabinet feet) or mobile (eg, including wheels or casters).

[0065] In addition, if Figure 1 As shown in , various sizes and door styles (solid or windowed) of cabinets of the present disclosure are contemplated.

[0066] The foregoing description of each embodiment has been provided for the purpose of illustration and description. The foregoing description is not intended to be exhaustive or to limit the present disclosure. Each element or feature of a particular embodiment is generally not limited to the particular embodiment, but even if not specifically shown or described, each element or feature of a particular embodiment is interchangeable and can be used in a selected embodiment when applicable. Each element or feature of a particular embodiment can also be changed in many ways. These changes should not be considered as departing from the present disclosure, and all these modifications are intended to be included in the scope of the present disclosure.
